, p. 3809 - 3812 (1993)
The new complex diindium triphthalocyaninate has been synthesized in crystalline form from the reaction of In-Sn alloy with 1,2-dicyanobenzene at 210 deg C.It crystallizes in the triclinic system, space group P with Z = 1 in a unit cell of dimensions a = 14.492(3), b = 13.179(3), c = 11.493(2) Angstroem, α = 113.96(2), β = 97.15(2) and γ = 66.13(2) deg.The structure was solved by Patterson and Fourier difference methods and refined by block-diagonal least-squares techniques to R = 0.0282, R' = 0.0372 and S = 1.22 for 7019 independent reflections having F0 > 4?(F).The centrosymmetric molecule consists of three phthalocyaninate ligands and two indium anions.The planes of the two peripheral ligands are parallel to each other, while the third central ligand is rotated about 37.5 deg in relation to the peripheral rings.The mean intramolecular distance between phthalocyanine planes is 2.954(5) Angstroem.The angle of inclination of the central to the peripheral planes is 5.2 deg.The indium anions are located between the phthalocyaninate ligands and have six-co-ordinate geometry.The four In-N bonds involving isoindole nitrogens from peripheral phthalocyaninates are shorter than the two involving isoindole nitrogens from the central phthalocyaninate .The intramolecular distance between indium atoms is 4.036(5) Angstroem.The shortest intermolecular distance between neighbouring successive phthalocyanine planes is 3.477(5) Angstroem.

X-ray investigations of the reactions of copper, tin and their alloys with gold, with 1,2-dicyanobenzene at 210°C have been performed. It was found that under the conditions used, gold does not take part in the reaction with 1,2-dicyanobenzene, but separates from the alloys. Copper and tin phthalocyanines are formed as the main products of the above reactions. The crystal structure of tin phthalocyanine (SnPC) has been determined. SnPc crystallizes in the triclinic system (a = 12.048(3) A, b = 12.630(3) A, c = 8.671(3) A, α = 95.85(5)°, β = 95.10(5)°, γ = 68.25(5)°), space group P1, Z = 2. The refined structure with anisotropic temperature factors have R = 0.041. The Sn atom is coordinated by four isoindole N atoms, the average Sn-N distance being 2.267(6) A. The SnPc molecule is not planar. The Sn atom is 1.1286 A out of the plane of the four coordinating N atoms.
